Yes, these are rechargeable. Charge via USB to outlet or PC/Mac. I've had them for a year and my daughter loves them.

The ones that I purchased, yes the battery is rechargeable. But, if there's a way to replace the battery, that would be great because the batteries suck now. They don't hold a charge for anything. I haven't checked to see if I can replace them. I'll check tonight though.

no they come with their own rechargeable battery packs. we use them everyday and have had no issues as of yet.

Yes. They come pre-charged. The manufacturer claims that these are better than other rechargeables at keeping their charge on the shelf, but they also suggest that customers who wanted top performance from the batteries might want to charge them fully before first use.

I Dont know if they are rechargeable but I bought them and they were dead from the start.

Yes, they are AA like any other, Not rechargeable so you can use them in anything that takes a normal battery. They will just last a lot longer. Hope that helps.

No, they are simply rechargeable batteries (excellent batteries for the cost) and like any battery of this type they rely on the devise they power for protection. Hope this helps, Have a great day.

No, they are not rechargeable batteries, they are regular batteries. I bought some Amazon brand rechargeable batteries, which are actually second generation Sanyo batteries, excellent batteries at a great price.

Unfortunately no. The installed batteries are long-lasting but no rechargeable battery I know of fits them.

Contrary to what others are saying here, these ARE rechargeable. ANY ALKALINE battery can be rechargeable; it's the CHARGER that matters--it MUST be for alkaline batteries. I have a few of them. Now they do not recharge very well, won't work for a smoke detector for example, but for other 9v devices that will work fine at 8-8.5v, 9v alkaline will recharge ok for those devices.

Yes, but they can be slightly discharged. It's best to charge them when they arrive. You won't do any harm because the charger is smart (unlike the old-school chargers, "dumb chargers," that used timed charging methods).

No they are not. They are 3.7 volt lithium ion rechargeable batteries. They are about twice as big as a regular AA battery.

They are rechargeable. The USB is to connect the glasses to a USB port in your computer.I found the recharging to be cumbersome time consuming, approx. 2 hours per set of glasses. I prefer 3D glasses w/batteries.
